Yijinhuoluo Banner National Fitness Sports Center is located at the intersection of Yiqi Zhasake Road and Wenming Road, and has a total construction area of 37,000 square meters and a height of 30 meters. The main function of the sports center is a 5,000-seat competition hall. The basement floor is a swimming pool while the overhanging part includes a variety of sports training rooms. The competition hall can be used for basketball, volleyball, badminton, gymnastics and other sports competitions.
The sports center has one basement and three floors above ground. The overall shape presents the shape of the lower floors retracted and the upper floors cantilevered. Above the second floor, the exterior cantilever is square. The roof is a 120m×120m square plane, and the outer periphery adopts a radially arranged large-span steel pipe intersecting frame structure. The center of the roof is a 71.2m-span rib-ring-type cable dome structure with a height of 5.5m. There are 20 radial cables and 2 ring cables. The entire building structure is novel and unique, especially the cable dome membrane roof structure at the top of the middle. The membrane structure covers a total area of about 4105 square meters. After completion, it will be the first large-scale cable dome membrane structure project in mainland my country.
The steel structure gymnasium project combines a variety of membrane materials (PIFE, PVC, EIHE) and thermal insulation materials for the cable dome structure, which satisfies the local climate requirements well. The cable dome structure has reasonable stress characteristics and extremely high structural efficiency. It is a modern structural system that best reflects the advanced materials, design and construction technology of contemporary buildings. The main structure of the cable dome can be divided into four parts: a continuous tension cable network composed of spine cables, diagonal cables, and loop cables, compression struts, central tension rings, and peripheral compression ring frames or ring beams.
The cable-membrane substructure consists of a membrane tensioned on the spinal cord and a valley cable arranged between the radial spinal cords. The application of prestress makes the cable dome evolve from a structure to a structure that can withstand the designed load. Therefore, the tension cable frame is the main bearing member of the cable dome structure; it realizes the advanced concept of “continuous tension ocean” structural mechanics. The stadium ring analysis frame is integrated with the outer roof sparse frame. The in-plane rigidity is very large, and the outer ring of the cable dome is close to the rigid constraint. The influence of the surrounding compression frame with greater rigidity can be ignored, and the boundary supported by the surroundings is adopted instead.
